Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611524, here are decompositions:

37 + 31611487 = 31611524
67 + 31611457 = 31611524
157 + 31611367 = 31611524
223 + 31611301 = 31611524
337 + 31611187 = 31611524
397 + 31611127 = 31611524
457 + 31611067 = 31611524
487 + 31611037 = 31611524

Showing the first eight; more decompositions exist.
